Planting Techniques and Cultivation Management Methods for Bletilla striata
Bletilla striata is a plant in the Orchidaceae family, genus Bletilla. Its tubers can be used as medicine and have an excellent hemostatic effect, with a very strong blood-coagulating action, and can be used in surgery as a substitute for plasma. It is cultivated in Sichuan, Yunnan, Gansu and other places, so how should Bletilla striata be planted? Let's take a look together below.
1. Site selection and land preparation
Bletilla striata has strong adaptability and no special requirements for soil. It likes warm, humid environments and is not cold-tolerant. When planting, it is advisable to choose loose, fertile, well-drained sandy soil rich in humus. After selecting the plot, plow it more than 20 cm deep, then apply barnyard manure and compost as base fertilizer, applying 1000 kg per mu. If there is no farmyard manure, compound fertilizer and organic fertilizer can also be used instead, applying 100 kg of organic fertilizer and 50 kg of compound fertilizer per mu. After fertilizing, mix it evenly with the soil. Before planting, shallow plow once, then rake fine and level, and make raised beds 1.5 m wide.
2. Propagation methods
Bletilla striata can be propagated by seeds and tubers, but sowing is relatively difficult and the survival rate is low, while tuber propagation is easier, so tuber propagation is mostly used in production. Tuber propagation is generally carried out from September to November. Dig out the Bletilla striata and select tubers of medium size and free from pests and diseases, requiring each piece to have one to two bud eyes. After mixing with plant ash, they can be planted. Open furrows on the bed surface at a row spacing of 20-25 cm, with a furrow depth of 5-6 cm. When planting, place the tubers into the furrows at a plant spacing of 10 cm, requiring the bud eyes to face upward, then fill with soil and press firm, water, and cover with grass.
3. Field management
After Bletilla striata sprouts, weed control should be done well. Management during the seedling stage of Bletilla striata attaches great importance to weed control, as weeds will affect the growth of seedlings. When weeding, it is best to pull the weeds by hand. After weeding, according to the growth status of the seedlings and the looseness of the soil, carry out timely intertillage and timely loosening of the soil. Whether intertillage or weeding, be sure to hoe shallowly to avoid damaging the root system.
4. Fertilizer and water management
Bletilla striata is a fertilizer-loving plant, and its fertilizer and water management is related to its yield. Generally, fertilizer should be applied once a month, and each application should not be too concentrated. Fertilizer can be diluted with water and then sprayed or poured, which can promote the root system's absorption of fertilizer and improve fertilizer use efficiency. After July-August, the plant stops growing and enters the dormant period. At this time, fertilization should be stopped, but attention should still be paid to the harm of weeds, pests and diseases. As for water management, Bletilla striata is a shade-loving plant and the soil should be kept moist often. In drought, water should be given in time, especially from July to September, watering once in the morning and once in the evening. But at the same time, it is also afraid of waterlogging, so in the rainy season, attention should be paid to drainage to avoid root rot.
